FEEDING MECHANISM FOR T HRASHlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 289,724, dated December 4, 1883.

Application filed October 10. 1883. (No model.)

To all whom it may concern:

Be it known that I, ZALMON S. STOCKING, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Feeding Mechanism for Thrashing-Wlachines, of which the following is a specification, reference being had therein to the accompanying drawings, in which- Figure 1 is a side elevation, partly in section, of a portion of a thrashing-machine the feeding mechanism of which is constructed in accordance with my invention and as apart of the machine. Fig. 2 is a like view illustrating my improved feeding mechanism made separate from and adapted to be applied to any ordinary thrashing-machine, and Fig. 3 is a perspective of my feeding mechanism detached and in condition for storage or trans portation.

Like letters refer to like parts in all the figures.

The principal object of my invention is to separate sticks, stones, and other similar foreign substances from the grain before its en trance into the machine and while it is being fed thereto. Other objects and advantages will appear inthe following description of the construction and operation of the parts employed.

A represents a portion of the frame-work and casing of any ordinary thrashing-machine B, the ordinary toothed cylinder, and O the usual concave of the same. These parts, as well as the feed table or board D, Fig. 2, are all of usual construction and form no part of my invention. From a pulley, B, on the cylinder-shaft a belt, B extends to a roll or cylinder, E, mounted over and extending across the feed-board, and provided with a belt-pulley, E. The cylinder or roll E is provided with teeth e,proj ecting from its periphery from end to end.

As thus far described, it will readily be seen that when motion is conveyed by the belt from the cylinder B to the roll E the latter will act to feed the grain to the thrashing-cylinder, and as plain feed-rollers have heretofore been so operated I do not claim such as of my invention; but the provision of teeth in the feedroll E facilitates the accomplishment of the main object of my invention, and I may add that in connection with the devices hereinafter described plain'rollers may with some degree of success be employed, and I therefore, while disclaiming such plain feed-rollers,broadly, do not wish to be understood as limiting myself to the use of a toothed feed-roll only.

As clearly illustrated in the drawings, I may adapt the remaining devices for use in and as a part of the ordinary feed-board of the ma chine, or in and as a part of asecondary feedboard separate from the machine, whereby my invention may be applied to machines already constructed. I first describe the former construction. I form in the feed-board and locate under the feed roll or cylinder E an opening, d, extending a distance equal to the length of the roll, and provide a drop-door, (1, adapted to close said opening. A spring, (1 of any suitable construction, is so arranged as to hold the door d in a closed position when not otherwise operated upon.

As thus far described, it will be seen that as the roll E is operating to feed the grain to the thrashing-cylinder B any sticks, stones, or other rubbish, 00, which may be mixed or held in the grain or straw will be-forced by the roll against the door (1, and it will be depressed, and as the grain or straw advances the stick or stone will pass through the opening d, and thus is separated from the grain and prevented from entering the machine. The instant that the stick or stone passes through the opening (I the spring (1* closes the door, and the surface of the feed-board remains continuous until other rubbish is met by the roll E. The above operation takes place whether the feed-roll E is provided or not with teeth 0,- but the provision of the teeth secures increased capacity of feed and a more thorough and ready sepa ration of rubbish from the grain or straw. A cover or casing, F, is provided to retain or deflect any foreign substances or rubbish that may accidentally pass the door d and be carried over by or be thrown from the roll E, and to serve as a guard to the operator of the machine in the operation of feeding the grain thereto.

ing to be opened to gain access to the roll E for any desired purpose.

In the form of construction which is designed A hinge or hinges, f, adapt the cas- I for application to thrashing-machines already constructed, and shown in Figs. 2 and 3, the sides f and ends f of the casing F are deep- 7 ened, whereby the casing as a whole is adapted to be placed or rested upon the ordinary feed board, D, of the machine. Feedopeningsfif" are formed in the sides, and a secondary feedboard, D, provided with an opening, (Z. A drop-door, d, and spring (1 are arranged within the case and below the feed-roll E, as hereinbefore described. A front foldable section, D", of the-feedboard D is provided, which, when thrown down on the ordinary feed-board, D, of the machine, forms an inclined (or, if desired, it may be a level) feeding-surface leading to the automatic feeding-roll E, and which, when folded up against the side of the casing, is in a compact condition for shipment or storage, as shown in Fig. 3. Screws or bolts f when passed through the sides of the feed-table, serve as means for securing the feeding attachment to the machine. Slots or a series of holes in the sides of the feed-table may be used in order to adjust the position of the attachment for the purpose of tightening the belt B or for other purposes. The operation in this form of construction is the same as hereinbefore described in connection with Fig. 1. In that construction the rubbish is delivered free from the machine, while in this form, as an attachment, the rubbish is held confined by the sides f f and the secondary feed-board D upon the ordinary feed-board, D, of the machine, from. which it may be re moved through an opening, f, formed in the side beneath the secondary feed-board.

I deem it proper to state that I do not limit myself to the exact relative arrangement of the parts, nor to the exact proportions herein shown; but I may vary the same in any manner and to any extent within the skill of persons conversant with the construction of thrashing-machines. For instance, I may omit the roll E and separate any rubbish by hand.

Having described my invention and its operation, what I claim is l. The combination, with a thrashing-cylinder, of a feed-roll and a :feed board or table having an opening under the feed-roll, a door for closing said opening, and means for yieldingly holding said door in a closed position, substantially as and for the purpose set forth.

2. The combination, with a thrashing-cylinder, of a toothed feed-roll and a feed board or table having a drop-door under said roll, and means for yieldingly holding said door in a closed position, substantially as specified.

3. The combination, with the cylinder of a thrashing-machine, of a feed-roll and a feed board or table having a drop-door and means for yieldingly holding said door in a closed position, substantially as specified.

4. The removable casing F, provided with V a feed-roll, a feed-board having a drop-door, and with means for yieldingly holding said door in a closed position, substantially as specified.

5. The combination of the roll E, feed-board D, door d, spring (1 cylinder B, and belt 13 substantially as shown and described.

6. The combination of the roll E, casing F, provided with feed-openings f f, and the feed-board D, having the foldable section D substantially as shown and described.

7. The combination of the casing F, provided with the openings f f f, with the roll E and feed-board D, having the drop-door cl, substantially as shown and described.

8. A feed-board of a thrashing-machine, provided with a downwardly-opening and upwardly self-closing door arranged and located away from the inner end of the feedboard, substantially as specified, whereby foreign substances may be separated from the material in transit to the thrashing-cylinder by hand or by means separate from the cylinder.

In testimony whereof I alfix my signature in presence of two witnesses.
